[Tutorial] Meizu m2 note bootloader unlock guide

Finally we have a guide to unlock the bootloader of Meizu m2 note. We need Mediatek SP Flash Tool, MTK phone drivers and the images/bin files for unlocking. No modaco superboot, no fake tutorials any more
Now here's the guide:
1. Download the files I provide
Then unzip it. You'll get a folder with FlashTool, Phone drivers and unlock images.
2.Install drivers for Mediatek platform.
3.Flash the temp-unlock-secro.img via Flashtool.
4.Flash secro.img, lk.bin, preloader_meizu6753_65c_l1.bin via Flashtool.
5.Disconnect USB data cable and power on the phone. If you see the "=>Normal boot" sign(it's quite small.......) in the left bottom cornor of the screen, then the unlock is done. You can now flash things in whatever way you like. The guide is over~~~
The full tutorial is here:https://mega.nz/#!zJxmBDAA!VyYLgPoOfx1P4O7WzSvKVycnbWnYPESzazZGOoIt15w

I hope xda-developers can help work out a recovery image:fingers-crossed::fingers-crossed: If you can port the recovery and it works well, just leave a comment here I need that very much
PS: I tried to port a TWRP recovery from Elephone P8000 but the screen is upside down I tried to add ro.sf.hwrotation=180 in default.prop but it didn't work And I also tried to add setprop ro.sf.hwrotation 180 in init.rc. It didn't work as well:crying: Who can help fix this? Or I need to compile the TWRP myself?)

M1 metal is powered by YunOS, and it have a system service called"AntiRoot". As we all know, the antiroot in YunOS is very powerful which is extremely hard to hack. Now you can only use Kingroot to get "Fake Root",which can't edit the system partition. I'm using m2 note(M571) so I can't help u about that, sorry

Oh, and remember this tutorial WON'T WORK on Meizu M571C (meizu m2 note China Telecom version ). We are still working on that but we don't have the phone to test our work.

Our bootloader has some problems, so it will always shows it is locked, but in fact it can be uocked by my method, and we are able to flash recovery partition. I ported one but it's buggy, so I won't release it until problem resolved. The screen is upside down but touch is ok. Th only way to fix it is to compile the full image, but my computer's performance is so poor.... Could u help me bro?

Sorry i cant help you.. my pc is not powerfull too and i dont have knowladge about it.. I wish someone can help u better.. and you can release custom rom or custom recovery for our Meizu m2 note.. peacee..

Hello, meanwhile thanks for excellent work, many were expecting this, this point is not clear 3.Flash the temp-unlock-secro.img via Flashtool. in which voice I load this? and also others from flash files,
do you think that will function on G firmware or is it better if he comes back to version A?
Excuse my English I am Italian, and use google translator

I tested it on 4.5.3A and 5.1.4.0A.
This guide only change the ""secro" partition, "preloader" and "lk"(bootloader). It does not depend on your firmware version. So be relax and try it
Hope your Google translater works well

How about in the guide:
And change the Scatter to this file:
Now choose temp-unlock-secro.img and select it.
but it always fails because it is not a scatter but .img

The scatter file is "MT6753_Android_scatter.txt", not the img maybe i insert a wrong picture there

what about mx4 pro (Exynos 5430 Octa) ?

hello we are new to and TWRP custom rom ??

I have build a TWRP recovery from the newest CM12.1 and TWRP source code.
Here's the link: https://mega.nz/#!ychBnTSb!wL6qicJ2KCpwnhHNImEhhk2OGuEKThxcDk2tj0iGuP0
Problems: Sometimes /cache partition can't be mounted. You can flash preloader, lk and secro partition again to solve this.
And the CPU Temperature clock doesn't work. It always shows 0 Degree...... I'll try to fix it.
Other functions works well Try it!
Before you flash it by Flash tool or fastboot or other tools, remember to remove /system/recovery-from-boot.p
That file will restore the flyme recovery at boot~

I would try but it is not clear how to use flash tool can make images of where to load the various files?
thank you

Run Flash Tool.
Load the scatter file first, then click the blank after "recovery", then load the recovery image. Click download then your phone will get TWRP recovery.
Remember to remove /system/recovery-from-boot.p first or your recovery will go back to flyme one

After installing the twrp have you tried to reflash a flyme rom ? Does it works or the official rom have some checks in the zip file to remove ?

[HOWTO] Flash TWRP and Flash CM+GApps [Meizu M2 Note]

Hi to everybody
I'm doing this thread because I've seen that there's a lot of confussion about how to install all this things properly, and I think that concentrating the wide-spread information could help you to get rid of this. First of all I have to thanks @aaawqw and @Moyster for their great efforts.
This is going to be a recopilatory of several sources and personal tips to help you to do this the easiest way. I'm not responsible of bricked phones nor your personal problems.
Please, read the full tutorial before doing anything, to avoid bricks and those things.
PREPARE THE RECIPE
Download these files:
- Unlocking bootloader tool: HERE
- TWRP image from Moyster (creator of LOS14 for our device): here
- If you want to install a modified version of FlymeOS, use this one from Romul35 from 4PDA: here. Original post
- Last LineageOS 14 build: from this thread. PLEASE DON'T FORGET TO THANK THE DEVELOPERS
- GApps: here I recommend the nano option. Choose ARM64 and Android version 6.0.
Put those three last files into your internal memory. If you've got an microSD card, I recommend you to put them into it (it's safer and easier).
UNLOCKING THE BOOTLOADER
To unlock the bootloader go to:
- Kevin.MX @aaawqw) post: here
Finally we have a guide to unlock the bootloader of Meizu m2 note. We need Mediatek SP Flash Tool, MTK phone drivers and the images/bin files for unlocking. No modaco superboot, no fake tutorials any more
Now here's the guide:
1. Download the files I provide
Then unzip it. You'll get a folder with FlashTool, Phone drivers and unlock images.
2.Install drivers for Mediatek platform.
3.Flash the temp-unlock-secro.img via Flashtool. (secro row)
4.Flash secro.img, lk.bin, preloader_meizu6753_65c_l1.bin via Flashtool. (secro, lk and preloader rows respectively)
5.Disconnect USB data cable and power on the phone. If you see the "=>Normal boot" sign(it's quite small.......) in the left bottom cornor of the screen, then the unlock is done. You can now flash things in whatever way you like. The guide is over~~~
The full tutorial is here
The unlock tool is here
Thank you for testing&trying!
If you've seen this spoiler and didn't thank Kevin, please go to here and thank him. This motivates him and gives him the recognisement he deserves.
- Robot Hijau 97 Youtube video: here It isn't in English, but may help if you find any problem or get lost during the unlocking. Leave him a like if it helped you.
This unlocking guide only works for M571 model. If you try this with a M571C (China Telecom) model, you'll get a bricked phone (very useful if you like paperweights )
THIS METHOD DOES WORK FOR M571H MODEL. DON'T WORRY, THE ONLY ONE THAT GIVES SOME ISSUES IS THE M571C.
The great user @aaawqw states "And Meizu M571C should use the same method of meizu m2 (mini), a shell script for frp unlock. But no recovery images yet…Different hardware and partitions"
Tips to unlock the bootloader easily:
- If you're going to do it from a Windows 10 or 8 pc, have in mind that to install unsigned drivers you'll have to unlock the feature in your pc. A guide to do this: here
- Select the images to flash and hit the Download button before connecting your Meizu (pressing Vol Down button). This will help you if it turns on and off and makes the flashing impossible.
- Download the guide or see the video to correctly follow all the steps. You don't want to lose your phone, don't you? Don't try to mix guides, because you may skip a step and brick your phone. The video and Kevin.MX guide are the same procedure, they both are safe.
INSTALLING TWRP
Once done this part, we'll proceed with the installation of TWRP recovery image. There are two ways, choose the easier to you:
- Flash TWRP from SP Flashtool (original idea from @widagdag. The post: here)
+Turn off your device
+ By using your pc or laptop, extract the TWRP zip for meizu m2 note, there's a file "recovery.img"
+ You can flash it via SP flash tool (clicking the recovery, then select the file)... then click Download, wait until finished!! (Check symbol)
+ You can reboot ur device now, unlocked bootloader and installed twrp!
*The profit is u didn't need to root first and install any flash tool such as Rash, FlashFire, Flashify, etc. saving you some time
Click to expand...
Click to collapse
- Flash the recovery image from Flyme:
+ Get root access (if you do, skip this step). You can get it downloading Kingroot: here. Just install this apk and follow the steps
+ Unzip TWRP zip into a known folder
+ Download Flashify from the Playstore
+ Grant superuser access
+ (Optional) make a backup of your current recovery going to backup tab
+ Tap Recovery Image
+ Choose a file
+ Find TWRP img that you unzipped before and flash it
Click to expand...
Click to collapse
INSTALLING CM AND GAPPS
We're close to the end of this post. The final step: installing your desired ROM and GApps. I will flash CM from the thread whose link is at the download section.
I hope you've put it into your memory (internal/external) as we said
Ok so:
- Turn off your phone
- Go into the TWRP recovery (Vol up+power)
- (Optional but recommended) Make a backup of Flyme, just in case you don't like the new ROM and would like to go back to Flyme. If it takes up too much memory, move it to your pc after making the backup.
- Go to Wipe menu
- Go to advanced wipe
- Select these:
+ System
+ Cache
+ Dalvik Cache
+ Data
- Swipe to do the wipe
- Go to install.
- Select your zip image (in my case the cm13 I downloaded).
- Install also the GApps zip file you downloaded
- Restart to System, and check what you've done.
Some final tips:
- Make the backup, seriously, it takes 10 min and you'll have a Flyme backup if you don't like CM.
- If you want to transfer all your apps and their data from Flyme to your new ROM, use Titanium Backup.
- If you want to install Xposed Framework, it's the same procedure: enter into TWRP, tap install, select the zip and swipe.
- This won't delete your images or videos, but I would recommend to transfer them to a microSD card or your PC.
- Yes, you need to do all this to install a custom ROM. Yes, even unlocking the bootloader. Don't try to skip a step if you aren't sure about what you're doing.
I think that's all, I'll update this post if I lost anything.
I hope this helped you to move into CM world. If you have any doubt don't hesitate to ask.
I know this seems exhausting, but trust me, it worths it. Welcome to the custom ROMs world in your Meizu M2 Note. Let the magic begin.
ADDITIONAL GUIDES
RELOCKING THE BOOTLOADER
If you want to relock the bootloader just follow this simple steps:
Flash the original recovery image from Flashtool of from Flashify (the steps are the same as installing TWRP). You can find this image here
From there, install an update.zip (download them from the official flyme web: here and put it into the storage )
Now you have flyme again with a locked bootloader.
INSTALLING FLYME WITH TWRP
It's very important that you don't install an update.zip from the original Flyme page, because you will cause a bootloop. To get the flyme updates, you can follow one of these two methods:
METHOD 1: 4PDA
-Download the modified zips from 4PDA: here]. Translate it to English. It's on custom firmware>Flyme
-Flash them from TWRP
METHOD 2: DO IT YOURSELF
-Download the update.zip file from the Flyme page
-Open it and remove the preloader- files
-Flash it from TWRP. It will give you an error: IGNORE IT.
Reboot and done, you've got Flyme and TWRP.
UNBRICK A PAPERWEIGHT
BIG THANKS TO @numpea FOR THIS:
This just a firmware that has all the partitions and can be used to unbrick to device using SPFlashtool
Here is the link:
FIRMWARE
- Flash temp_unlock_secro.img with sp flashtool like you do when unlocking the bootloader.
- When done, disconnect the device and add the firmware to sp flashtool. You need to select "format all+download", click on "Download" and connect the device. The flashing process will start. After it finishes, the device will start again.
You wil notice that you lost your imei number you can add it back by:
Using MTK Engineering Mode (does not requires root)
Open engineering mode » Click on Engineer Mode (MTK) » Swipe left to Connectivity » click on CDS Information » Radio Information
Click on phone 1 if you want to change your sim 1 or choose Phone 2 to change sim 2 IMEI, follow this guide:
For Phone 1: “AT+ EGMR=1,7,”YOUR NEW IMEI NO” (make sure you add a space in between AT+ & EGMR)
For Phone 2: “AT+ EGMR=1,10,”YOUR NEW IMEI NO” (make sure you add a space in between AT+ & EGMR)
Using Chamelephon (requires root, but much more easier)
Just copy the IMEIS from the phone's box and put them into the app.
hope this is helpful

Pretty much covered all, just state the Armv7 Android level API 21 64bit, 5.1 Micro or Nano for gapps. They might get confused on what to choose.

Great work lol
Another thing is…ShevT's recovery has no problem in cache partition.Only my broken recovery did… So remove the cache fixing partAny problem just send me a private message. I'll check when i have time.
---------- Post added at 04:00 PM ---------- Previous post was at 03:58 PM ----------
And Meizu M571C should use the same method of meizu m2 (mini), a shell script for frp unlock. But no recovery images yet…Different hardware and partitions…
Another thing is, Kingroot is not suggested. It cannot be detected by Flashfire and some other tools. And cannot be replaced by SuperSU. So Kingo Root+SuperSU might be better.

Newb needs help rooting, unlocking Bootloader and getting a Custom ROM for ALE-L21

Hey there,
I need help, hope you have some for me . I want to use the 6.0.1. OpenKirin OmniROM on my phone and struggle even figuring out a way to get there.
I just bought a used ALE-L21 DualSIM phone with the B602 Build and EMUI 4.0.3 installed. The device is not rooted, nor has its bootloader been unlocked. The EMUI update service does not offer me any patches.
Could someone please line out to me which steps I have to take in order to root my ALE-L21 and get this ROM to work?
Disclaimer: No, I'm not just a lazy moron who does not want to read other topics on this forum - I'm a mere user with less-than-average knowledge of Android development or stuff like that. And I just can't make complete sense of the various posts I've found, since English is not my mother tongue and there seems to be a whole bunch of ways to do certain things with a phone. Well, since obviously I don't want to brick my new phone, I'm not too sure how to best puzzle together the pieces this Forum offers me. It would be insanely helpful if I could get a list that reads out something like:
1. Action - Source (for needed files, e.g.) - Result, on to step 2
2. Action - Source (for needed files, e.g.) - Result, on to step 3
3. ... and so on...
Okay, just so you see that I'm not entirely lost, I'm gonna show you the picture which is currently in my mind.
From what I understand so far, there's the following steps to get there (please rectify or rearrange steps as far as needed):
1. Update the device to Vanilla EMUI 4.1, Build B895 or B896 (I am currently downloading the B896 Build from this forum - which one is recommended? My phone is DualSIM)
2. Unlock Bootloader (What's the best way to do it? Huawei CS? Heard it's not even sure you get an answer. DCUnlocker? Wants money... Please help me clarify)
3. get TWRP 3.1.1.0 (I already have the IMG file, how do I get it to run on my phone?)
4. Root the device (I'd like to go with MAGISK, does anyone have a link for a MAGISK build confirmedly working on ALE-L21?)
5. Do some magic with TWRP (Which steps exactly?)
6. Flash the ROM Zip file via TWRP
7. Flash Gapps via TWRP
Is that about it?
As I said, please feel free to add to/adjust my list!
Thanks in advance,
Pako

If you haven't already install minimal adb tools on computer (windows) found here :
http://bit.ly/2jxX4ya
You then need to unlock bootloader using minimal adb tools and the unlock code
Unlock Code:
http://bit.ly/2z9EFhV
Unlock Bootloader Method in this thread here:
http://bit.ly/2oIASBs
After you are done unlocking the bootloader
Install twrp find that here :
http://bit.ly/2ok9BTi
There was a tool that was here somewhere to install twrp but I will link to my copy here
http://bit.ly/2ATBgRP
What you do is put the twrp image file in data folder
then change the name of the twrp file to TWRP_3.1.1-0_ALICE.img or
edit the install.bat file line data\fastboot.exe flash recovery data\TWRP_3.1.1-0_ALICE.img to the name of your twrp file
Once twrp is installed then you can pick which rom you want
The 6.0 roms arent going to be supported anymore so i suggest going for 7.0 ROM
I'm on AOSPA which is the cleanest and has good battery life
To install 7.0 rom you need B895 or B896 found here on the first post:
http://bit.ly/2jypIij
this is installed through twrp (which is accessed when Phone is off by holding volume up + power then let go once it vibrates or connect the phone to the computer and then type adb devices then adb reboot recovery in minimal adb tool)
once in twrp you need to install the B895.zip or B896.zip file then reboot your phone will boot into emui
you need to install twrp again as B895 or B896 wipes it
After installing twrp you can then install any custom rom of your choice
let the rom boot and then go back into twrp and install gapps found here: "http://bit.ly/1JOWjUqi recommend nano or even pico pick am64 7.1
I would also recommend installing Galactic forced deepsleep http://bit.ly/2ANVdbS

Hey there,
thank you very, very much for your comprehensive walkthrough! (Almost*) everything worked to perfection and I am now a happy user of OpenKirin's OmniROM 6.0.3. mod! Yeah, no 7.x... but I'd prefer to wait with that until the "issues" section of AOSPA does not contain any relevant things anymore. OmniROM seems to have no issues anymore, so I'm content with my choice. I will now follow your last advice and flash the Deep Sleep Mod to improve my device's battery life, and then I'm just happy.
* = The only issue I encountered was when having flashed TWRP, the device booted to the crappy EMUI eRecovery instead of TWRP. I solved this issue using this advice from another thread.
So, once again, thank you! All you xdaDevs, keep on developing ways to improve people's lives with their android devices!
Cheers,
Pako

No sim card detected on custom roms

I have a XT1572 (Indian variant dual sim) . The sim card works good on both 6.0 & 7.0 (official roms) however remains undetected on any custom rom . Any guidance would be of great help .

Using magisk? It will cause that. Flash magisk uninstaller and reboot system once before flashing a new rom.

Tried but no success

So I was on stock mm , had magisk -uninstalled and rebooted afterwards . Installed RRemix(RR-N-v5.8.5-20171230-clark-Final) . Again no sim . Attaching two screen shots for your reference .
One thing to note I have a dual sim variant and under all custom roms imei of only one is being displayed .
This whole thing is very strange since I could run Lineage very easily on the same phone sometime back , roughly around Oct'17 . Used the phone on stock nougat afterwards .

Anyone ?

@antariksh
I am very well aware of the fact that lineage would not run on nougat modem. Have tried aicp rremix unofficial lineage etc . The issue remains the same no sim detected .
What I have done for installation -
fastboot install marshmallow/nougat build (depending upon the custom rom)
flash latest twrp
in twrp factory reset (don't mount/unmount anything, all default)
rom boots but doesnt detect any sim .
details of only one imei of the two is displayed under about phone .

Have you tried this version with this guide?
P.S: Nougat has 9 system.img_sparsechunk's. So flash accordingly and then try any other custom ROMs.
P.P.S: Flash Modem twice if you get any 'prevalidation failed error'

I'm afraid it must be your device issue.
Cause last week I followed the same steps to Flash Stock Nougat and went back to NucleaROM.
You sure you are using Nougat Modem based Custom ROMs?

Very very strange because I do recall that all these custom ROMs used to run fine without any such stupid issues back in October last year . its really disheartening. Yes I am using nougat firmwares for nougat modem compatible ROMs and mm firmware for rhe mm compatible one's . Its just that be it any custom ROM this thing won't work at all ! Is it anyhow related to recovering phone from brick state because I do remember that I had to flash the bootloader on a memory card in order to get the device up ?
Appreciate your efforts brother.

i have similar problem

HI there , I hope my constant requests aren't bothering . If they are kindly let me know & I shall refrain in future .
I just realised one thing . On installing nougat fastboot file from " https://forum.xda-developers.com/moto-x-style/general/xt1572firmwareclarkretasiaindiads7-t3735257" as per suggestions I get model as XT 1572 on connection to PC . Although in recovery mode when connected (twrp) the same pc recognizes the phone as XT1575 . Is it normal ?

Yep. It is normal. TWRP was probably based out on XT1575. But it doesn't matter.
Only modems differ between XT1575 and XT1572.

Flash the MM firmware, make sure the modem has no validation issues, then flash the custom ROM you want. Flashing with Nougat firmware won't allow boots. Also, sometimes the MM firmware just doesn't work, and flashing stock firmware will "rejuvenate" it.

I wanted to try installing it on 6.0 . The install process didn't initiate saying that the bootloader (A**52) isnt compatible.
Plus I noted that on downgrading to 6.0 from 7.0 the loader and gpt bin gave failure errors in fastboot.

GPT is not downgradeable and it doesn't need to flash successfully. Also, one you are on 0xA052 firmware, you can't go back, but you can edit the rom's files and make it skip the bootloader check. This is a quote of myself on how to do that from the LOS thread,
"Extract the ROM zip into it's own subdirectory. Then go into the folder META-INF, then com, then google, android, then open updater-script in a text editing program. I prefer Notepad++. Locate the line that says assert getprop ro.bootloader. Should be line 2. You can either add your bootloader by copying another item, or this is easier, edit a line already there, such as "|| getprop("ro.bootloader") == "0xA048" ||" and replace 0xA048 with 0xA052 or the bootloader your device has. Then save it by going to the root folder, not the folder labeled "lineage-14.1-xxxxxxxx-nightly-clark-signed", but the folder with the folders install, META-INF, system, and etc. Select everything by dragging your cursor over all the files, then right-click, send-to, compressed zip. Name it anything, then copy it to your device however you prefer, I just sideloaded it in TWRP. If you get an error talking about a digest file, you might have accidentally deleted something you shouldn't have."

Magisk 23 to 24 ruined

Hi!
I had Magisk v23 working fine with Magisk hide but then I upgraded to v24. Magisk app successfully installed and shows Magisk not present. And when I try to DirectInstall Magisk, I get verification failed error. Attached both screenshots.
Now, I have installed and confirm TWRP is working but do not know how to make Magisk working again and it seems it gonna be a wipe. Any help appreciated.

This guide expects me to know what ROM I have. Thing is, I do not know what my device really is. It's running a ROM that I do not recognize (My post: https://forum.xda-developers.com/t/...l-and-odin-cannot-flash.4372669/post-86069051). I do not have the sources for it so I cannot acquire the required two files. Ramdisk is Yes as per my screenshot but I cannot follow the rest of the guide without the files.

try this
Check hardware and software info Galaxy:
*#12580*369#
Android 9 shows almost certainly a stockrom Pie .

I just TWRP it. It went smoothly. I love a new ROM but need to know what device is it.
Download mode say it is SM-G950N
Android say it is SM-950FD
Both SIM slots have the same IMEI number. This part is beyond my understanding.
I have Odin and know the basics. Just need to find a ROM I can go for: What official I should flash first and what custom. Any recommendation?

As soon as you make a TWRP total backup, you can see your boot.img and move a copy to your internal sd-card. There it can be picked up by Magisk and patched....Magisk will put it in your download folder on the internal sd-card ...
for the best Rom ask members with your S8 phone. I'am on the S7 Edge.

I have been trying to make the total backup but I do not see any boot.img:
And I do not see the file in the Device/TWRP/Backups:
Again, I must be missing something obvious. And as per the Magisk guide, I need the boot.img

magisk 24 is ****, it's bricking MediaTek powered Samsung phones

Boot.img from TWRP backup
In clockworkmod kernel and recovery are backed up as IMGs. But in TWRP it is boot.emmc.win Anybody know how to convert jt to boot.img? Help will be really appereciated. Sent from my HTC One X using xda app-developers app
forum.xda-developers.com
I must tell you that my custom rom for the s7 gives me the boot.img as the first file as soon as i open the zip.
the boot.img can also be reached by downloading the right stock rom for your phone. In that case it is the best practice to patch the whole
AP file by using Magisk.
